How Do You Make A Density Column?
A density column displays multiple layers of liquids that differ in density and solubility. Liquids with higher densities form layers near the bottom of the column, while those with lower densities form layers higher up. Adjacent liquids cannot dissolve in each other, which prevents mixing of the liquids. There is no limit to the number of layers in a density column, as long as each layer is of different density and is insoluble in the liquids above and below. Pour corn syrup into the bottom of a clear container. The amount of corn syrup will vary according to the size of the container. There simply needs to be enough to create a visible layer. Pour a layer of water on top of the corn syrup. Add a few drops of food coloring to the water. The food coloring will remain in the water, as it is insoluble in both the corn syrup and vegetable oil. Pour a layer of vegetable oil on top of the water. This completes a three-layer density column that is very resistant to disturbance. If the liquid
